Product Description

Function analysis
EPC coating can prevent mechanical and thermochemical sand sticking of castings, improve the rigidity of foam plastic models, prevent deformation during mold embedding, and help to rapidly discharge the thermal decomposition gas of EPC patterns. Then why does EPC coating have so many functions? Let's analyze from six aspects.
The lost foam casting coating has these six characteristics: (1) high strength and stiffness, preventing deformation of the mold during molding and damage from dry sand; (2) High fire resistance to prevent sand adhesion on the surface of castings during pouring; (3) Excellent breathability, which can quickly export the gasification products of the pattern; (4) Strong adhesion to prevent coating cracking or even peeling during the production process; (5) Good adhesion, easy to apply a certain thickness of coating when in use; (6) Good sintering and peeling properties, that is, forming a coating shell that is easy to automatically peel off after pouring, thus obtaining castings with a smooth surface.
mix time
The stirring time during the preparation process of lost foam coating has an impact on the performance of the coating. Generally, the stirring time should not be too short. The stirring process is a means of diluting the paste like coating to meet the coating requirements. Stirring has a separating effect on the block like substances in the coating, and water has a certain wetting effect on the powdered solid under strong force, while also causing mixing of the various components of the coating.
Research has shown that the length of stirring time has an impact on the apparent uniformity (block, particle, uniformity), leveling, adhesion, viscosity, coating thickness, and other indicators of lost foam coatings. The following are the research results:

Time (min)	performance	Flatness (cm)	Attachment amount (g)	Viscosity (mPa. s)	Coating thickness (mm)
